Application of MR-1 Shewanella oneidensis EPS in degradation of plasticizer

The invention provides application of MR-1 Shewanella oneidensis in degradation of plasticizers, and belongs to the technical field of biological treatment of environmental organic pollutants. EPS in an MR-1 Shewanella oneidensis culture solution is extracted and added into the polluted water body to be used for degrading the plasticizer, the EPS is any one of total EPS, S-EPS, LB-EPS and TB-EPS, and the plasticizer is DBP. The EPS extracted from the MR-1 Shewanella oneidensis culture solution is high in DBP degradation efficiency, long in duration time, environmentally friendly and free of pollution. 本发明提供了MR-1奥奈达希瓦氏菌在降解增塑剂中的应用，属于环境有机污染物生物法处理技术领域。本发明提取MR-1奥奈达希瓦氏菌培养液中的EPS，并将其加入到污染水体中用于降解增塑剂，所述EPS为总EPS、S-EPS、LB-EPS和TB-EPS中的任意一种，所述增塑剂为DBP。本发明从MR-1奥奈达希瓦氏菌培养液提取出的EPS对DBP降解效率高且持续时间长，环保无污染。
